Technical Abstract

Disclosed are a power supply control device and an electronic apparatus. The power supply control device includes a power supply unit configured to generate an output voltage from an input voltage, and an output discharge unit configured to start to discharge the output voltage when an instruction to disable the power supply unit is given, and continue discharging the output voltage until the output voltage falls below a predetermined threshold voltage or until a predetermined delay time passes while the output voltage does not fall below the threshold voltage even when an instruction to enable the power supply unit is given. The electronic apparatus includes a power supply device including the power supply control device as a main constituent, and at least one load configured to operate while supplied with an output voltage from the power supply device.

Patent Claims
2 claims

Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.

Claim 6

Original Legal Text

6. The power supply control device according to claim 1, wherein the power supply unit is one of a part or a whole of one of a switching regulator or a linear regulator.

Plain English Translation

A power supply control device regulates power delivery in electronic systems, addressing inefficiencies and instability in voltage conversion. The device includes a power supply unit that can be either a switching regulator or a linear regulator, or a portion of either. Switching regulators convert input voltage to a desired output voltage using switching elements, offering high efficiency but requiring complex control. Linear regulators provide stable output voltage by dissipating excess power as heat, offering simplicity but lower efficiency. The power supply unit may function as a standalone regulator or as part of a larger power management system. The device ensures reliable power delivery by dynamically adjusting voltage levels based on load conditions, improving energy efficiency and system performance. This design is particularly useful in applications requiring precise voltage regulation, such as consumer electronics, industrial equipment, and telecommunications systems. The integration of switching or linear regulators allows flexibility in power management, accommodating varying power demands while maintaining stability and efficiency.

Claim 8

Original Legal Text

8. The electronic apparatus according to claim 7, wherein the output discharge unit is further configured to continue, even when the enable signal including the instruction to enable the power supply unit is received, the discharge of the output voltage until the output voltage falls below an under voltage locked out detection voltage lowest value set to each load.
